- Do not use open fire near the workplace, do not smoke or hold any very hot objects. There is a risk of accident! Keep a fire extinguisher at hand;
- Ensure adequate ventilation of the work area. Fuel vapors are toxic;
- The fuel system is under pressure. When opening the system, fuel may escape under pressure. Collect the fuel with a rag. Use safety glasses;
- When working with diesel engine fuel system components, take special precautions. This applies especially to injectors. Keep in mind that the fuel pressure when leaving the injectors is about 1100 atmospheres. Do not allow any part of the body to come under the fuel stream;
- Hose connections are secured using band or clamp clamps. Clamp clamps must be replaced with band clamps or clamps of the latest design. A special device is available for installing band clamps, such as HAZET 796-5;
- Thoroughly clean connections and adjacent areas before opening;
- Place the removed parts on a clean lining and cover. Use polyethylene or paper for this. Do not use lint-producing rags for this;
- Carefully close open parts or install technological plugs if the repair will take some time;
- Install only clean parts. Remove spare parts from their packaging only immediately before installation. Do not use parts that have been stored unpackaged (for example, stored in a toolbox);
- If possible, do not work with compressed air when the fuel system is open. If possible, do not move the vehicle while doing this;
- Do not use sealants containing silicone. Silicone elements that get into the engine do not burn out and damage the oxygen sensor.
Safety precautions when removing the fuel tank:
- Before removing the tank, drain the fuel from it or pump out the fuel using a pump specially designed for this purpose;
- The fuel tank is removed from the underside of the vehicle. Before disconnecting the tank mounting clamps, place a jack and shims underneath the tank;
- An empty tank is explosive and cannot be disposed of in this form. Before disposal, the tank must be cut into pieces. Make sure that no sparks are generated. To do this, hand over the fuel tank to a specialized company;
- After installing the tank in place, start the engine and check the tightness of all connections.
